' J15 glove is made and often resultsin the necessity to reestitch the seams.

An object I seek 'is to alleviate if notjwh'olly v eliminate this di'iculty by employing a yielding plunger action, which action, however, -20 applying to the plungers only,--the glove supports being vertically ixedand unyielding. The flexibility of the plunger-action takes care of thesudden shock incident to Vthe engagement of the turning elements and izvertically immovable supports holdv the glove in correct and non-distorted shape while the turning progresses. Another object is to provide an oscillatory movement of the plungers f in combination z-30 with the reciprocatory action at the beginning of the turning, thus giving thetip yof the glove iinger a'slight twist which Afacilitates its entry into'the tubular support. vThis Y feature is especially applicable to the thumb as this member is-stifer and more rigid'than the lingers.

A further object is to provide,-more especially for the two outer supportunits, a tilting action, allowing them to bend orswa-y toward each other for the'p'urpose of lmore easily inserting the ends of the'supports in the fingeropenings of the glove -and-'also to providefa more compact assembly o'f'the glove-support lends over which'y to pulldown `the wrist band of the glove. f ,n

Still further objects relate to the' ability to readily re-position theplung'ers and glove- Isupports inV their respective lseats whereby *gloves of various sizes andvstyles may be accommodated, and-l also tothe design ofithe parts and the method of' assembling or disassembling these elements whereby they-may -be quickly attached to or detached from the V]g r'operp'arts of the glove-turning machine.

-Inthe drawings, l represents the 'upperf yvertically 'reciprocable Vbracket of the gloveturni'ngmachi'ne hereinbefore referred toas 'In th'e upper bracket'l is a longitudinal "slot 3, the sidestliereof, near the top, being lflaredoutward, providing as'eat 4 in which y are stationedthe four glove-plunger hous- 4inafter described, and'in the accompanying ings 5 with tapering sides 6 which closely fit the seat 4. The object of this construction is so as to be able to re-position the housings along the bracket seat to any desired center to center distances therebetween for the purpose of accommodating different sizes of gloves. The housings are secured in their seats b v the nuts 7, and to readjust their positions all that is required is to relax the nut, manually slide the housings along the bracket and then retighten the nut.

Reciprocable in each housing is a plunger 9 having a reduced portion 10 on which is fixed a collar 11 operating in an enlarged bore 12 of the housing.

Surmounting the top of the housing and screw-threaded thereto for adjustment purposes, is a cap 13, and abutting on the top of this cap and threaded on to the portion 10 of the plunger is a nut 14. A helical spring 15 thrusts on the top of the collar 11 and on the bottom of the bore of the cap 13, thus holding the plunger normally and inertly as shown in Fig. 1. The nut 14 provides axial adjustment of the plunger relative to vertical movement within the housing.

Fitting the screw-threaded portion 16 of the housing is a sleeve 17 serving as an abutment against which the collar 18 fixed on the plunger may shoulder to resist the upward movement of the latter within the housing. By the use of this sleeve 17 the stroke of the plunger within the housing may be varied.

It is therefore obvious, firstly, that the plunger may be adjusted to various vertical, inert positions in and with reference to the housing; secondly, that the stroke of the plunger within the housing may be varied; and thirdly, that upward movement of the plunger within the housing may be resisted with greater or lesser potency,-all by the possible combination of adjustments made by the nut 14, the cap 13 and the sleeve 17.

It will be observed that the lower end of the plunger, at 19, is flattened and made broader and thinner than elsewhere. portion, which I term the turning head of the plunger, operates to draw the sides of the glove finger tips together as they enter the glove-supports and leaves more space transversely of the direction of expansion of the tubular support blades when used in con junction with the type of glove-support which I patented May 12, 1925, No. 1,537,794, than would be the case was the plunger end made of a uniform round section throughout. This increased width of the plunger end necessitates some provision to prevent the possible rotation of the plunger in the housing,- otherwise, should the plunger turn, say ninety degrees, the breadth of the plunger end being too great to freely enter the glove-support width-ways of the latter, there would be a conflict between and injury to the parts when they mutually engage.

This v I therefore provide means to control this rotation of the plungers,preferably eliminating all rotation of the finger plungers but allowing a slight oscillation of the thumb plunger.

InEFig. 1 there is shown a straight key-Way 20 in the lunger, engaging which is a screwkey 21. his provides straight reciprocatory movement of the plunger. In Fig. 2 I show a construction particularly applicable to the thumb plunger, due to the fact that it is somewhat more diiiicult to turn the thumb than it is the fingers of the glove. A spiral key-way 22 is cut in the plunger and a collar 23, ada table of being rotated to different circum erential positions in the enlarged bore 12 of the housing, carries the screw-key 21 which engages the key-Way 22 and imparts a twisting movement simultaneously with the reci rocatory movement of the plunger.

e action of this twisting effort of the plunger on the glove thumb end is somewhat analagous to that of wringing a cork into a bottle to more easily seat it therein.

Were it not possible to move the screwkey 21, in Fig. 2, to different circumferential positions, then on making adjustments of the plunger, varying its vertical and inert position Within the housing, the relation between the turning head 19 and the glove-support would not be constant. In other words, to hold the turning-head 19 so that in any one of various positions (as in Fig. 1) its flat sides will always point in the same direction, horizontally, then the screw-key must, at different times, engage different portions of the length of the key-Way 22. This screw-key cannot, therefore, be located in the housing as a fixture, as is the same element in Fig. 1, but must be susceptible of circumferential movement with respect to the housing so as to accommodate itself to any change in the vertical location of the plunger when at rest,--or when the nut 14 abuts on the cap 13.

To iXedly secure the collar 23, carrying the screw-key 21, in any predetermined position the set-screw 24 is rovided.

In Figs. 5 and 6 I il ustrate my improved glove-finger support incorporating features which make it particularly adapted for use on the fore and little fingers of the glove. The construction of the extreme upper end of the support is similar to that disclosed in my Patent No. 1,537,794, hereinbefore referred to, but in all other characteristics there are marked dissimilarities.

Mounted on the lower bracket 2 of the machine are the four glove-finger supports and the glove-thumb support, the blades of the latter being preferably made as shown in Fig. 7. It will be understood that these glove supports xed on the stationary lower bracket of the glove-turning machine operate in co-action with the yieldingly mounted glove plungers on the movable upper bracket.

. ,Each of theglove lsupport unitassemblies 1 comprises a pedestal having inclinedV sides 26 which bear on the similarly inclined surfaces 27 of the slot 28, which latter runs length-ways of the bracket and is of sufficient length toinclude the four supports when separated to their maximum center distances. A bolt 29y depends from Vthe pedestal and on its lower end, which extends beyond the depth of the bracket, is a nut 30 and washer 31. By these means each pedestal may be independently secured to the bracket and may also be moved therealong by releasing the nutf30. This :feature of adjustability of the vpedestals to obtain different center to center positionings thereof is very advantageous asV it provides kfor the turning of a variety of sizes of gloves with'the least amount oflabor involved in re-positioning the parts so as to accommodate eachrespective size of the glove Ato be turned.

The upper end of the pedestal is bifurcated and between the ears 32 the swing-blockv 33 is j ournaled over the pin 34. A downwardly extending portion 35 of the swing-block contacts with one end ofthe helical spring 36 which is disposed in a hole 37 in the pedestal. A screw-plug 38 on which the opposite end of the spring abuts serves, when screwed in or out of the hole, to increase or decrease the tension of the spring.

On the Lipper opposite side of the swingblock is a horizontal arm 39 in which is the adjusting screw 40,-the 'latter Vcontacting with the pedestal at V41.*By actuating this screw 40 the support may be placed in various upright positions, either perpendicular or inclined to either side thereof.

Rising from the swing-block 33 is a shank V42 screw-threaded to receive the glove-support holder 43 which carries the glove-support blades 44.A

After continued use, especially in the operation -of turning heavy, stiff gloves, these glovesupport blades often become bent or otherwise unfit for service. This requires replacements l and I have provided in my improved construction a simple method of attaching the blades to the holder. In fact I have illustrated two quick detachable designs, either of which I have found satisfactory.

In Figs. 5 and 6 I show the side and end views and in Fig. 11 a transverse section through one of these blade holding structures.

rlhe holder 43 has a reduced portion 45 and in this portion is bored a taper hole to receive the taper pin 46. A diagonal scarf 47 is cut through the reduced portion and a square sleeve 48 mounted thereover, the shanks of the blades being interposed, one on each transverse side of the holder. A slight drive of the pin 46 will lock the parts together.

In the modified form of the holder shown in Figs. 8 and 9, the body of the holder is milled at opposite sides to receive the thickness of the blades and a square hole 49 made to `allow the ears 50 of the blades to enter.

-A block 5lk separates the ears and a taper pin as to be mountable over the shank 42, the n tapped hole being at 53. y

On my previously patented glove-turning machine, previously referred to, I employ gripping members which grasp the wristband of the glove on the1upward stroke of the movable bracket and pull the glove off the glove-supports.

To facilitate the operation of gripping the glove I provide means to hold the wrist-band outwardly of the support blades so that the grippers may more easily engage it. To this end I insert between the blades a fender 54 which, like the blades, lies interjacent the scarfed portion 45 and the outer sleeve 48. Thus by the expansion of the split portion ofk the holder 43 caused by the forcing of the taper pin 46 into the hole in the holder, all three members,-the two blades 44 and the fender 54 are firmly locked to the holder.

The fingers of a glove lie substantially in V lthe same plane, but the thumb inclines outthumb than the finger supports in their respective openings in the glove. This is particularly true in the case of wrist-band glovesV which usually come to the machine with the wrist-bands turned inwardly and upwardly within the glove space,-often so far `Vupn' wardly that the thumb opening is closed.

I largely kovercome this trouble by curving the thumb-support blades inwardly, as seen in Figs. 7 .and 7a. The operator is then able to draw the glove downwardly and inwardly of the top of the support which has the effect of giving'thel thumb ak slight transverse, inward movementl effecting an easier entrance of the end of the support into the thumb opening. n

The vertical adjustment features of the glove plun'gers have already been dealt with. Those .effecting the glove supports comprise the vertical adjustment of theholders 43 on the shanks 42,-.a check-nut 55 serving to lock the holder in any adjusted position. Also, the tilt or incline in which the outer glove .supports are held in normalposition is taken care of by the adjusting screw 40 which positively holds-the support against movement in one direction,-the compression of the spring 36 allowing the support to oscillate in the opposite direction.k Both plunger and support units aremanually adjustable to differentpositions .on their respective brackets.

Having thus described my invention, what I claim is:
